Easily spins the rear with a little left foot braking in second gear! (lotsa fun)
But the best part was the unexpected bonus when i put the fuse back in. Im not going to tell anyone yet, to avoid the placebo effect. Go try it, and i will tell you what I noticed in a couple days. Don't worry; no warning lights stay on, the wipers return to their normal operation. It was a very subtle improvement I noticed.
So get out there! If it is raining your wipers will remain on and it will be super easy to verify RWD.
You got PM! ohhh and with a JB3, you dont even have to do a brake boost to rip them loose, all you do is tap on the gas and ur going sideways!
